Donna said: “To say this challenge was hard, is an understatement. Canoeing 31km – the equivalent of the English Channel – biking 21km and then climbing 19km up and over the highest mountain in England without rest is not for the faint-hearted.

“Each individual element of this challenge is really a piece of cake and anyone could do that, but to lump them all together and do it without sleep over 24 hours is something else.

“No matter how much you prepare, there is always the potential for problems at some stage.

“The teamwork was outstanding. The support that they gave to each other when the going got tough and fatigue started setting in, is what made this challenge such a success and the reason we smashed it in only 23 hours.”

The team was hoping to raise £8,400 for The Royal Marines Charity, but the group has smashed that target by raising £10,000 so far.

Donna said: “I am so pleased we smashed our target of £8,000 and the great news is there is still more to come in.

“We would like to thank everyone who sponsored the team. We are very grateful for all the support we’ve received.”

Donna is already planning her next challenge in aid of The Royal Marines Charity in June 2018.

The fitness coach will be running a bootcamp challenge with the Royal Marines at Nailsea and Backwell Rugby Club.
